Oh, and for what it is worth, CERN is finishing up the largest accelerator ever made, and when it goes online it will have enough energy to produce miniature black holes.

The CERN scientists believe this will help us better understand the multi-dimensional theories involved in string theory, but I cannot help but wonder what would happen if these "really small micro-black holes" did not evaporate according to Hawkings theories.

If there was some chance that one of these black holes absorbed another particle, and then another, and another ... well it wouldn't be good for Earth.

If I'm not mistaken, there was once a theory that stated the reason we cannot find super-advanced life in the universe is because all of them were at some point destroyed by the same experiment.
